The published experimental values of the refractive index of liquid hydrogen have been correlated by calculating and comparing the values of the Lorentz-Lorenz ratio as a function of wavelength.Because of the scatter found by this analysis, it is proposed Topic: Liquid hydrogen.

The pumping characteristics of liquid-solid mixtures of parahydrogen (slush hydrogen) were investigated using a centrifugal type liquid hydrogen pump with a specific speed range of 1600 to 3100.Performance tests at 8,000, 11,000, 14,000, and 19,000 rpm an Topics: Hydrogen., Centrifugal pumps.
The published data on the surface tensions of normal hydrogen from three investigations are apparently in disagreement by about 10%.In this note it is shown that these data are actually in agreement within about 1% if properly computed.The resulting conco Topics: Hydrogen., Surface tension.
Frequency shifts due to hydrogen spin exchange collisions are discussed for the hydrogen maser and the hydrogen storage beam tube.The combined effects of spin exchange and cavity pulling in the hydrogen maser are evaluated with emphasis on frequency error Topics: Masers., Storage tubes., Frequency stability., Spin exchange., Hydrogen.
